Abstract

(57) [Summary] [Purpose] When replenishing seedling mats to the seedling table of the rice transplanter, the tension of the vertical feed belt can be released so that the seedling mats can be smoothly replenished from above. [Structure] In a rice transplanter comprising a seed feeding table 3 having a vertical feed belt 1 and a seedling splicing sensor 2 and capable of reciprocating in a lateral direction, which is obliquely arranged above a seedling take-out plate 4, the vertical feed belt One of the upper roller 5 and the lower roller 6 which hangs 1 is pulled and urged in the tension direction of the belt, and the longitudinal feeding belt 1 is loosened so that the tension of the belt is released by turning on the seedling joint sensor 2. It is constructed by erection.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seedling vertical feeding device for a rice transplanter in which a vertical feeding belt can be loosened when a seedling mat is supplied to a seedling mounting table.

[0002]

[Prior Art]

 Conventionally, in a rice transplanter composed of a seedling table that has a vertical feed belt and a seedling splicing sensor and is capable of reciprocating in the horizontal direction, is installed obliquely above the seedling pick-up plate, the vertical feed belt is used during vertical feed. It is always in tension even when it is being driven or stopped.

[0003]

[Problems to be solved by the device]

 However, when replenishing the seedling mat from the upper side of the seedling mounting table to the vicinity of the seedling take-out plate, the stopped vertical feed belt becomes a resistance and the replenishment work becomes difficult. The problem was that it was easily broken by the feed belt, and the vertical feed belt was always in a tensioned state, so it was easily stretched and damaged.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such a problem and to preferably implement it with a simple structure. Therefore, one of the upper roller and the lower roller for mounting the vertical feed belt is The vertical feed belt is erected freely so that the tension of the belt is released by turning on the seedling joint sensor while pulling and urging in the tension direction.

[0005]

[Action]

 Therefore, in the state where the seedling mat on the seedling mounting table is vertically fed, it is possible to accurately feed the seedling mat vertically as usual by the tensioned vertical feeding belt, and the seedling splicing sensor is turned on. When the splicing is performed, the vertical feed belt is released from the tension and is loosened. Even if the seedling mat supplied from above the seedling table comes into contact with the vertical feed belt, the vertical feed belt is loosened. Since the elasticity of the seedling mat does not damage the seedling mat, the belt can be rotated by the weight of the seedling mat and the seedling take-out plate can be supplied smoothly.

【Example】

 Fig. 1 shows a side cross-sectional view of the main part. A seedling take-out plate 4 having each seedling take-out port is horizontally installed at the planting part of the rice transplanter, and the seedling take-out plate 4 is reciprocated laterally above the seedling take-out plate 4. The moving seedling mounting table 3 is installed obliquely, and the vertical feed belt 1 and the seedling joint sensor 2 are provided on the lower side of the seedling mounting base 3. The vertical feed belt 1 is hung on the upper roller 5 and the lower roller 6. At the same time, a supporting guide 7 for supporting the upper surface of the belt is installed above the middle of both rollers 5 and 6, and a driven cam 8 vertically hung from the shaft of the lower roller 6 via a one-way clutch is provided. The vertical feed belt 1 is intermittently driven when rotated by one angle to one side.

Further, the shaft portion 5 a of the upper roller 5 is rotatably supported along the guide groove 9 so as to be movable in the extension direction of the belt, and the bearing 10 fitted on the shaft portion 5 a is mounted on the upper solenoid 11 When the seedling mat is located above the seedling splicing sensor 2 and the sensor 2 is turned off, the upper rod 5 is actuated by the solenoid 11 when the suction rod 11a is retracted from the suction rod 11a. When the vertical feed belt 1 is in a tensioned state while being urged upwards, and the seedling joint sensor 2 is turned on, the solenoid 11 is deactivated and the vertical feed belt 1 is released from the tension and loosened. To be configured.

It should be noted that the vertical feed belt 1 can be driven at an intermediate portion, the upper roller 5 side can be driven by a motor, and the lower roller 6 can be made compact and can be pulled in the belt tension direction. It can also be configured so that it can be activated.

Therefore, in the state where the seedling mat on the seedling placing table 3 is vertically fed, the seedling joint sensor 2 is turned off, and the vertical feed belt 1 is tensioned by the solenoid 11 while being pulled and urged in the direction of arrow a. This means that the seedling mat will be vertically fed accurately by the tensioned vertical feed belt 1, and when the seedling joint sensor 2 is turned on and the seedling joint is carried out, the solenoid 11 is activated. When the vertical feed belt 1 is released, the tension of the vertical feed belt 1 is released and the vertical feed belt 1 is loosened. Even if a seedling mat supplied from above the seedling placing table 3 comes into contact with the vertical feed belt 1, the vertical feed belt 1 is loosened. Therefore, the elasticity of the seedling mat does not damage the seedling mat, and the belt can be rotated by the weight of the seedling mat, so that the seedling pick-up plate 4 can be supplied smoothly.

[0010]

[Effect of the device]

 As described above, according to the present invention, when the seedling mat on the seedling placing table 3 is vertically fed, the vertical feeding belt 1 can be tensioned to accurately feed the seedling mat vertically as in the conventional case. When the sensor 2 is turned on and the seedling is spliced, the tension of the vertical feed belt 1 can be released and loosened, so that the seedling mat supplied from above the seedling mounting table 3 is loosened in the vertical feed. Even if the belt 1 comes into contact with the seedling mat, the elasticity of the seedling mat does not damage or collapse it, and the belt is rotated by the weight of the seedling mat. In addition, since the vertical feed belt 1 is tensioned or loosened, it is possible to improve durability without stretching or ruining as in the conventional case, and a simple structure. It has the advantage that can be suitably carried out in the.
